BRICK-MACHINE.

Specification of Letters Patent.

Patented N0vl-.6, 1906.

Application filed October 10, 1905. Serial No. 282,202.

To all whom it may concern:

Be it known that I, DAVID P. SANDERS, a citizen of the United States, residing at Readin in the county'of Berks and State of Pennsy vania, have invented a new and useful Brick-Machine, of which the following is a specification.

This lnvention relates to maclunes for the formation of blocks, bricks, and similar artifrom the machine and placed on the drying- A further object of the invention is to rovide a multiple molding-machine in w iich the mold-box roper is divided into a lurality of charm ers or spaces by slidaillym'ounted artition-blocks, which are withdrawn en wise before the material has fully set, the artitions thus acting to trowel or smooth t e edges of the blocks.

A still further object of the invention is to provide a multiple molding-machine in which the mold-space is arranged for the reception of a pallet that is divided by transverse grooves or spaces, and the mold-box is correspondingly provided with .movable partitions that enter between said spaces, the partitions being first removed from place in order to permit the raising of the pa let and the blocks from position within the mold-box.

With these and other objects in view, as will more fully hereinafter a pear, the invention consists in certain nove features ofeonstruction. and arrangement of parts hereinafter fully described, illustrated in the accom anying drawings, and particularly 'pointe out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advanta es 0 the invention.

In t e accompanying drawings, Figure 1 is a perspective view of a block-rnoldnrm machine constructed in accordance with t ie invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a plan view of the pallet detached.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawin s.

The working parts of the mac 'ne are supported upon a suitable frame, which in the present instance comprises three standards 10, that are rigidly connected at their upper ends by flanged cross-bars 11 and 12, said bars constituting the front and rear stationary side walls of the moldbox. The inner face of each of the bars is provided with a shoulder 13, on which rests a pallet 14, and the pallet in the present instance is formed of a large number of strips that are slightly spaced from each other and are secured to and carried by a pair ofbars 15, the ends of which project beyond the allet-surface proper'and form carrying-hand es.

he bars 15 rest on a number of vertically-- movable slides 16,- the opposite edges of which are adapted to suitable guides 17, bolted or otherwise secured to the standards, and each slide is connected by an abutment 18 to a rocker-arm 19 on a rock-shaft 20, that is adapted to suitable bearings in the lower portion of the frame of the machine. At one end of the rock-shaft is an operating-lever 21, which may be moved from the full-line position shown in Fig. 2 to the dotted-line position shown in the same figure in order to elevate the pallet and the blocks carried thereby.

. Both the front and rear walls of the moldbox are provided with slots for the assage of partition-plates 22, the rear en 8 of said plates being supported in grooved arms 23,

that extend outward from the lower portion of the bar 12, and said partition-plates are held depressed by a stri 24, that extends over the whole series of p ates at a point just to the rear of the bar or mold member 12.

The upper rear portions of the standards are provided. with bearing-blocks 26 for the reception of a shaft 27, to which are secured a number of pinions 28. Intermeshing with the pinions 28 are rack-bars 29, that are held down in engagement with the pinions b a transversely-extending strip 30. The orward ends of the rack-bars are pivotally connected to the rear ends of the slidable partitions 22, and when the shaft is turned by the crank 32 all of the artitions are moved simultaneously to or ii mold-box.

At a point above and to the rear of the mold-box is arranged a mixing board or om position within the IIO 75M. 1M MW m a trough 35, on which the concrete or other cement mixture maybeplaced prior to its introduction within the mold.

In the operation of the device the partitions are all adjusted to the position shown in Fig. 1, and the material previously mixed and placed in position on the board or partition is drawn over by a smoothing-trowel or the like, and all the mold-boxes are.filled, the surplus material bein troweled ofi inthe usual manner. The era 32 is then turned, and all of the partitions are simultaneously withdrawn from the mold-box, the partitions sliding in e agement with the surfaces. of the blocks or ricks before the latter are fully set and finis the surfaces. When the partitions are fu y withdrawn, the operiazting- I ever 21 is moved from the full-line position to the dotted-line position of Fig. 2., and its movement, transmitted through the rockshaft 20 and pitman 18, elevates all of the slides 16, and the pallet 14, together with all of the moldedrests, is raised to a position above the top of the mold-box in position to be removed to the drying floor.

With an apparatus constructed in accordance with this invention a large number of bricks may be simultaneously made-at comparatively small expense.

Havin thus described the invention, what is claime -is 1. The combination in a molding-machine of a mold-box open at its opposite ends and having slotted front and rear walls, partitions arranged within said slots to divide the moldboxinto mol'rlin aces, a pair of supportingbars arranged ieibw the mold-box, pallet members secured to said supporting-bars, a plurality of movable slides arranged under saidbars, a rock-shaft, rocker-arms thereon, and eonneeting-rods extending between the rocker-arms and slides.

2. The combination in a molding-machine, of an open-ended mold-box having slotted front and rear walls, slidably-mounted artitions arranged to divide the IHOld-bOX'lIllJO a. series of mold-spaces, guiding and supporting means for the partitions, racks pivotally
